Abstract (en)

[origin: WO2021144695A1] A process for treating a material, such as by calcination or reduction processes, is disclosed. The process comprises reacting hydrogen and oxygen in a reaction chamber and producing heat and steam, discharging steam from the reaction chamber, using the heat to treat the material and produce a treated material, and returning at least some of the steam discharged from the reaction chamber to the process. An apparatus is also disclosed.
